Seat Assembly - 2nd Row - LH (With Broken Seat Track Motor) (Remove and Install)

Correction Code 13050501

Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
Only perform this procedure if the seat is unable to move backward and forward in order to allow access to all fasteners that secure the seat.. If the seat is able to fully move, refer to Seat Assembly – 2nd Row – LH (Remove and Install).

This procedure requires drilling through the gearbox housing to access the gear in the outer track, inserting a square drill bit though the gear and into the motor, and using a drill to spin the motor. This causes the seats to move, which provides access to the fasteners that secure the seat. This procedure requires replacing the outer track.

Special tools required for this procedure:
